The site I do seo for a site that has over 15 sitemaps, but one of the sitemaps keeps having a problem with google downloading it. Google returns cant access the sitemap. It meets the url and size requirements, and when I send it through validators it has no errors. Yet every week it seems to fail again, then when I resubmit it is will be approved for another week before failing again. This is the only sitemap that is doing this.
Any idea if there is a problem here that I can address. Any help is greatly appreciated!
